Seeing a ride shut down with the lights on is disheartening at the least, and ruins the illusion you have come to enjoy at the most. Dinosaur made me soooooooo sad when it e-stopped that I couldn't ride it for months.
On the other hand, Spider-Man is so impossibly good, that I finally had to take of the 3-D glasses and look everywhere but the screen. While I figured out a few things, it is so good that even that didn't ruin it for me.
That said, most rides don't stand up to having their tires kicked under bright lights.
